Safety Assessment and Hypoglycemic Effect of Moringa oleifera Lam. Seed Lectin (WSMoL) in Alloxan‐Induced Diabetic Mice

Journal of Applied Toxicology, Volume 46, Issue 11, Page 3973-3988, November 2026.
ABSTRACT Moringa oleifera Lam. seeds contain WSMoL, a lectin previously studied for toxicity and pharmacological effects. In this study, we investigated WSMoL (10, 25, or 50 mg/kg i.p.) for acute and 14‐day repeated‐dose toxicity, as well as genotoxicity, in Swiss mice.
